Earlier this year, a sinkhole opened up within the National Corvette Museum in Bowling Green, Ky., taking down eight Corvettes 60 feet below the show floor. Since then, the natural disaster has proven profitable for the museum, prompting its board to make the hole a permanent attraction.

Autoblog reports the hole will be see its size modified from 40-feet wide and 60-feet deep, to 25-feet and 45-feet wide with a depth of 30 feet. There will also be a dirt embankment where up to two of the most damaged of the eight Corvettes will be displayed.

The modifications will take place in September after the museum celebrates its 20th anniversary and the grand opening of the NCM Motorsports Park in late August. CFO Christy Thomas added that if interest wanes or if the museum feels the need to retire the exhibit, the modifications would make filling in the remainder of the sinkhole a possibility.

For now, though, the hole has been a profit magnet, drawing a 71 percent boost in admissions from a 59 percent increase in visitors between March through late June of this year, with no clear signs of abating in the near-term.
